I've got stage-2 ThinLTO+SPGO build of clang using the flags you included but can't reproduce the error - do you have any more information that might be relevant to reproducing the error? Otherwise I'll continue to dig at the rest of the info you've provided to see if I can see an obvious cause of failure, and see if we can find some way to verify a fix without having to repeatedly land and revert until the fix is confirmed.
